Did Galileo discover Saturn’s rings?
The rings of Saturn have puzzled astronomers ever since they were first seen by Galileo in 1610, during the first telescopic observations of this planet. Although he saw the rings first, Galileo did not know what they were. They appeared to him as 'ears' or lobes either side of the planet.
Did Galileo discover that Saturn has ears?
When Galileo viewed Saturn through his telescope about 400 years ago, he wrote that the gas giant planetgiant planetJupiter and Saturn are the gas giants of the Solar System. The term “gas giant” was originally synonymous with “giant planet”, but in the 1990s it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier volatile substances (which are referred to as “ices”).https://en.wikipedia.org › wiki › Gas_giantGas giant – Wikipedia had "ears." Those ears, elongated bulges on either side of the planet, were Saturn's rings. Galileo could not discern the rings through his small telescope.
Did Galileo see Saturn’s moons?
Galileo Galilei was the first to observe Saturn with a telescope in 1610. Because of the crudeness of his telescope, he couldn't determine what the rings were. He incorrectly guessed that there were two large moons on either side of Saturn. Two years later when he viewed Saturn again, the "moons" had disappeared.

What was Galileo view of the solar system?
The discoveries that Galileo made using his telescopes helped to prove that Sun was the centre of the Solar System and not the Earth. His observations strongly supported a Sun-centred model known as the Heliocentric modelHeliocentric modelHeliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center.https://en.wikipedia.org › wiki › HeliocentrismHeliocentrism – Wikipedia, previously suggested by astronomers like Nicolaus Copernicus.May 9, 2019

Galileo Galilei's observations that Venus appeared in phases — similar to those of Earth's Moon — in our sky was evidence that Venus orbited the sun and contributed to the downfall of the centuries-old belief that the sun and planets revolved around Earth.Jul 5, 2011
What did Galileo think Jupiter was?
On January 7, 1610 Galileo first viewed Jupiter through his telescope. What caught his eye was not the planet itself, but three bright stars that were arranged in a perfect line on either side of the planet. Galileo sketched Jupiter and the three stars, thinking at first they were simply a chance alignment.
What did Galileo think about the planets?
Galileo was cleared of charges of heresy, but was told that he should no longer publicly state his belief that Earth moved around the Sun. Galileo continued his study of astronomy and became more and more convinced that all planets revolved around the Sun.
